Documentation for the IT Service Desk to handle ID Card Suffix issues. ID cards are encoded with information in the magnetic strip when they are produced. This information includes the nine-digit ID number printed on the card and a two-digit issuance code (or suffix) not printed on the card. When the suffix encoded on the card does not match what is in other systems that the card may be used for (e.g. dining, card-swipe door access, card-swipe authentication to printers) the owner of the card will not be able to successfully access those services with the card.
